[gme-users] How to invoke a Java BonComponent

[Gürkan Özhan]

Hi Kevin,
   I've tried a similar code to TestMgaLayer1 as below:

...
		Apartment.enter(true);

		// create and open mga project
		MgaProject project = MgaProject.createInstance();
		project.open("MGA=C:\\Gurkan\\PhD\\ModelTrans\\Multi2BinaryFAM\\Model\\FAM_BinaryInstMsc_4SIMMono.mga");
		project.beginTransaction(null);
		JBuilder jBuilder = new JBuilder(project, this);

		JBuilderObject focus =
(JBuilderObject)jBuilder.getRootFolder().getRootModels().get(0);
		Collection selected = null;
		int param = 0;
		invokeEx(jBuilder, focus, selected, param);

		project.commitTransaction();
...

Note that, the this parameter to JBuilder constructor is this class,
which is a BONComponent

 However, I get a runtime error if I execute that code (starting from
new JBuilder(project, this); statement):

Exception in thread "main" org.isis.jaut.ComException: No such
interface supported
(0x80004002)
	at org.isis.jaut.Dispatch.changeInterface(Native Method)
	at org.isis.gme.mga.MgaAtom.<init>(Unknown Source)
	at org.isis.gme.bon.JBuilderFolder.<init>(Unknown Source)
	at org.isis.gme.bon.JBuilderFolder.<init>(Unknown Source)
	at org.isis.gme.bon.JBuilder.<init>(Unknown Source)
	at org.isis.gme.bon.LSCCodeGen.startCodeGen(LSCCodeGen.java:2485)
	at org.isis.gme.bon.LSCCodeGen.main(LSCCodeGen.java:2499)

Apparently, the iID of the new interface in the format of
"{XXXXXXXX-XXXX-XX...}" is not recognized. What is this string anyway?
Every Dispatch object has that.
   Best regards,

Gurkan
